The answer is 4260, you can do 200 plus 60, then add to 4000
Answer:
3x+2y
Step-by-step explanation:
Find the rectangles attached
Area of a rectangle = Length * Width
A = A1+A2
given
A = 30cm²
A1 = 3 * x
A1 = 3x
A2 = 2*y
A2 = 2y
Substitute
30 = 3x+2y
Hence the required equation is 3x+2y = 30
Answer: B. 
Step-by-step explanation:
The confidence interval for the population mean is given by :-

Given : Sample size : n= 100
Sample mean : 
Standard deviation: 
Level of confidence = 0.95
Significance level : 
Critical value : 
Then, 95% confidence interval for the population mean will be :-

The model shows that we are to arrange the factors based on the terms in the square box. The factored form is (5x+2)(2x-1)
<h3>Factorizing quadratic equations</h3>
Factorization is a way of simplify. Given the equation 10x² -x - 2
Factorize
10x² -x - 2
10x² - 5x + 4x - 2
5x(2x-1)+2(2x-1)
(5x+2)(2x-1)
We are to arrange each term of the factors in the square box
